Abstract: Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. The data security techniques disclosed herein also enable the use of smart contracts to transfer funds associated with payment obligations. A node may receive a transaction indicative of a settlement condition of a smart contract being satisfied. Accordingly, the transaction may be compiled into a block of a blockchain and routed to the smart contract. The smart contract may direct a node to transfer funds in accordance with the payment obligations.

Abstract: High bulk, absorbent paper having a relatively high MD elongation at rupture, and a substantially greater stress/strain modulus in the lowest one-third of its range of MD extensibility--preferably when wet--than equally machine-direction-stretchable, purely dry-foreshortened (e.g., dry-creped) paper having substantially identical MD elongation at rupture. The process includes a differential velocity transfer of a wet-laid embryonic web having relatively low fiber consistency from a carrier to a substantially slower moving, open-mesh transfer fabric having a substantial void volume; and thereafter drying the web while precluding substantial macroscopic rearrangement of the fibers in the plane of the web. The differential velocity transfer is effected without substantial compaction of the web by avoiding substantial mechanical pressing, centrifugal slinging, air blasting, and the like.

Abstract: A floating dry dock for a boat comprising a tubular, boat-supporting platform made from a planar array of interconnected PVC conduit (or similar material) and a pair of vertical, buoyant, tubular side walls connected to the platform. The dock includes an atmosphere venting system with its outlet above the water surface at all times connected to the base conduit platform and a freely positionable pump in fluid communication with the platform conduit array, which allows for the pumping of water into and out of the platform tubular array, which controls the depth level of the platform. The vertical side wall conduits are sealed and filled with air to add positive buoyancy to the platform to prevent it from sinking beyond a desired level. The diameter of each conduit of the ballasting tubular array for the platform is selected to accommodate boats of varying displacements. In operation, the device can be stored by floating adjacent a sea wall or the like.

Abstract: An improved process to produce a novel tissue which becomes ply-separable during the papermaking process. In a first embodiment of the invention a two-layered stratified web is formed, having a first layer comprised of a relatively low consistency slurry of long papermaking fibers and a second layer comprised of a high consistency slurry of relatively short papermaking fibers. In a second embodiment of the invention, a stratified web having three layers is formed, comprised of well-bonded layers separated by an interior barrier layer. These improved tissue products need not be creped from a creping roll with a doctor blade in order to exhibit ply-separability, and they may be creped in a single step to form a finished product which is creped all the way through.
